To all'iohom it may concern:

Jltirss I-I. ALL N, citizens of the United States, residing'at Argetita, in the county 5. of-lultskihnd State of'Ar-kansas, have infvented cert'ainnew and useful -Improveine n ts" iii Vehicle-A xles; and we 'do declare j t he"following to be a full, clear.and-exact;

.yieldingly supported, and the axles th'us relieved of a great deal of the' stra'in to which they are usuallysubjected.

\Vith this and other objects in view, the invention consists of certain novel features of construction, combination and arrangeinent. of parts as will be more fully described and particularly pointed out. in the append ed claims In the accompanying drawings: Figure l .is a side view of a portion of the front axle of an automobile, embodying the invention -and showing the casing of the springs in section; Fig. 2 is a vertical crosssection of the same on the line of Fig. 1; Fig. 3 is a central vertical longitudinal sectional view of a portion of the rear driving axle; Fig. 4 is a vertical cross section of the same on the line 4-4 of .Fig. Referring-inert: particularly to the drawings, 1 denotes the front, steering axle and 2 denotes the rear driving axle. of an automobile. The front axle has pivot ally connected to its end, by knuckle joint 3, a spring casing 4 to which is hingedlyconnected the arm 5.

The casing 4 is preferably in the form of a rectangular oblong box havin; an open outer end and lower side. The open lower side is closed by a removable bottom plate 6 having side flanges 7 which are bolted or Otlltil'V/lm: secured to the sides of the casing near its lower edges as shown. The open outer end 'of the casing is closed by an end plate 8 which slidably engages the outer end-of the casing and is preferably slightly curved as shown. The arm 5 of the axle has a squared inner portion and its inner end ishingedly ,I'Se"itlmown that we, Jon-x T. Davis and connected to the sides of the casing as shown at t).

On the-outer end of the arm-5 is formed the spindle 10 of the stub a-xle thus formed, said spindle projectingthiough a +l|lttlbl0jl3$iitl go in th e end plate whereby said :plate will slide up anddown on-the outer end otgthe casing whe the arm is swung upward] y orfdownw-ardly by the wheels when pass-mg over obstrn :tionsfor rough surfaces.

letween the upper side of the arm 5 and 5 the-.top-o'f the casing are arranged coiled springs 11 which yieldii gly.support the weight of the vehicle on thezarm The tension of the springs is regulated by adjnstin screws 12 arranged in the upper-7 side of the-casing and having, their-inner ends engaged with adjusting plates 13 arand tllchpperside of the casing} I The rearaxle 2'has its inner-portion revoiubly mounted -in a casing 14 in which are arranged ball bearings 15 with which the axle is engaged. The end of the axle 2 projects beyond theend of the casing 14 and ranged between the upp'erends oftlie springs into a spring casing 16 which is arranged, on 50 the end of theaxle casing 14 assh'own. Connected to the end of the axle by a universal joint 17 is an arm 18. The arm 18 is revolubly mounted in hall l'iearings 15) arranged in the spring casing '16 and the spindle 20 on the 35 v end of the arm is engaged with and projects through the outer end plate 21 of the spring casing. The plate 21 slidably engages the end of the casing in' the same manner as the end plate 8 ofthe front axlecasing.

In the easinglti of the rear axle, l'ietween the ball bearings 19 and the'upper' side of the casing, are arranged coiled springs 22 which yieldingly support the .weight of the \'el1ic|e. The springs 22 are provided with ,95

tension adjusting screws 23 and plates A arranged above the same and in the upper side of the casing 16 as shown. one side of the casing 16 is preferably removable and is scored in place by suitable fastening screws which are engaged therewith and with threaded apertures formed in lugs 26 on the casing.

()n the inner 'side of the casing 16 are formed curved guide flanges 27 which hold the ball beariugslt) in place when the same and the axle arm and spindle swing up and down.

From the foregoing dcseription taken in connection with the. accompanying draw- 11o 15- 'ried by said and and slidably engaging the d slidably engaging the end of the spring cas- 5 and the-minor details of construction may v -be resorted tofwithout. departing fromthe principle orsacrificing an of the advan-" tages of this invention, as efined in the appended claims. I

'deseribed our invention what I we claim i's:v" 1. An axle having a vertically swinging arm and spindle, a casin inclosing said arm and having an .open en an end plate'carend of the casing, and rings arrange within the easingand bearing on said arm.

2. In combination with an axle, of a stub axle movably attached thereto, a'casing 2 -e gin 'theoonnecting end of said stub ax e an having an open end, an end plate carried by the stub axle and 'slidably engaging the open end of the casing, and means engaging with the stub axle for 2 yieldingly supporting the .weight of the vehicle,

easing and engaging said plates. 4.

. 3. An axle having a ertically swingin arm and spindle, a casing iiiclosin sai arm and having an open end, an en plate carried by said am and slidably engaging the end of the casing, coiled springs bearing at oneend against the said arm, ad'usting *plates bearing against the opposite en of the springs, and tension screws mounted in the he combination of an axle casing, an

- axle revolubl mounted therein, a spring casing arrange on the'outerend of said axle casing, an axle arm and spindle. having a universal joint connection with the end of the axle an end plate fixed to said arm and ing, and springs arranged between said axle arm and the casing.
